Guild Wars: Eye of the North®

Halloween is fast approaching, the spirits are getting restless and trick or treaters are preparing to walk the earth in search of sweets. It doesn't matter how good their costumes are, they're not going to be able to compete with some of the Halloween events happening in the gaming world. Guild Wars, Aion, City of Heroes and Global Agenda are all running special Halloween events. Read on for an overview of the horrors that lie in store.

Guild Wars - The Return of the Mad King of Thorns

The Mad King is preparing to visit the kingdom of Tyria, and his spirits are already at large. Head to Lion's Arch or Kamadan and search for the Mad King's steward, he'll be the one dressed in candy. You'll hear news that the Mad King's Lunatic Court are hatching a plan to release the seals that keep their pumpkin headed leader confined for most of the year, turning the world into an everlasting Halloween party. It might sound like a good idea, but with special Halloween items on offer for completing these special quests, you'll probably want to put a stop to their mischief for the loot.

Come October 31st the Mad King of Thorns will make several appearances at the Lion's Arch and Kamadan, launching a series of ridiculous and deadly games. If you win, you get a special Halloween hat, if you lose, you suffer instant death (until you respawn, of course). If you're especially eager to get into the halloween spirit, a couple of ghoulish new Halloween costumes will be on sale at a reduced price until November 21st.

It's Halloween and someone has stolen all of the sugary treats. Even the winged immortals of Aion need sugary treats, so it's time to get them back, by beating the sugary crap out of some nearby wildlife. The Shulacks who were entrusted with watching the sweets instead ran off with them, and started gifting them to local animals. As a sugar obsessed member of the immortal race of Daeva, it's up to you to get them back. Retrieve enough goodies and you'll be rewarded with Revel Chocolate and the Pumpkin King's blessing, both of which grant powerful buffs to your character. You'll also get mystery boxes which could contain anything from potions from scrolls to enchantment stones. The event will kick off on October 27th.

Zombies are invading all cities and dimensions in City of Heroes, spewing onto the streets, milling around, eating passers by and generally stinking up the place. Smite them with lasers, riddle them bullets or immobilise them with firm and repeated facepunches for special Halloween rewards. Look out for the circles of power that are appearing all over the place, these will summon much larger monsters into the world. You'll need a team of superheroes to take them down.

You'll also be able to do a bit of your own trick or treating, going door to door in Paragon city. If you're lucky the occupants of the home you pester might just give you a rare costume set. If you're really lucky you might get your very own slightly rubbish inanimate rock, which can then be thrown at enemies for very little damage. If you get a trick, you could find yourself fighting a horde of enemies, defeat enough of these and you'll be able to combine Halloween salvage to gain an additional costume slot for your character.

If you get your hands on one of the classic costumes, go door knocking while wearing it, and you might get a tip off for a special new quest, a mission to find the mysterious Malleus Mundi artefact. There are a ton of badges and awards to be earned in the event, which will last until October 31st. Check out the full list of rewards on the City of Heroes Halloween 2010 event page.Global Agenda - Oasis Checkpoint of Doom

A crate load of new masks are up for grabs in Global Agenda's Halloween event. If you're over level 30, you'll be able to boot up the game between October 27th and October 31st play a new Defence map in the Raid list called the Oasis Checkpoint of Doom. This map will pit you and nine others against waves and waves of incoming enemies. Defeat them and you could win yourself one of thirteen new masks. If you defend well enough and take down the final boss, you'll get a guaranteed mask and along with a slew of other rewards.

For more information on the Oasis Checkpoint of Doom check out the Global Agenda site. If you fancy getting involved you can join the PC Gamer US editors for some epic base defence action in the Play With PC Gamer event later today.
